I've now watched that video, and I'm going to say what I disagree with.
First, he claims that Copilot/GPT only needs more data and more compute to get better. I disagree. It needs both, for sure, but I think it needs more.
Also, it won't get any more data! As LLM's are used more and more, the data fed in will be more and more like what they would generate anyway, which will lead to the models overfitting on things and getting worse.
He claims that bots make mistakes quickly and that allows iteration. This is true, but the iteration will probably be more like bogosort than anything intentional. (Bogosort is famously very expensive.)
Why is it like Bogosort? Because even good "prompt engineers" are more or less creating enchantments on the fly to coax information out of a black box. To me, that seems like a more or less random search. Hence, random search, random sort, it's like Bogosort.
He claims reviewing the code is 100x faster than writing it in his experience. Well, yes, because you don't dive into as much as the original writer did. Reviewers only have so much time, so they spend only as much time as they have. They could spend more and catch more bugs.
He claims that the AI will (eventually) take instructions from you and run them directly. He says they won't generate the code, they are the code.
They can only do this if they are Turing-complete, which if they are the typical neural nets I've seen, they cannot because data can only flow one way. Turing-completeness requires data to be able to flow conditionally, forwards, and backwards, and any combination. These models cannot do that. They would also need recursion.
He claims they have reasoning capabilities. I claim they only have the appearance of reasoning, borrowed from the reasoning capabilities of the humans that wrote the material used in the training sets.
His example of the cards is good, but not that impressive. It didn't tickle any Turing-completeness.
Those are my thoughts as I watched it. It was pretty good though. It was convincing. I know I'm weird in that I just cannot be convinced.
